Abstract:
Objective To study the expression of nuclear factor-kappaB (NF-κB) and the counts of lymph vessels in laryngeal squarnous cell carcinoma and polyps of vocal cord tissues, and explore their clinicopathologic significance and correlation in the course of laryngeal carcinoma. Methods SP immuno-histochemical method was used to detect the expression of NF-κB and the counts of lymph vessels on the routinely paraffln-embedded sections of the specimens from 50 cases laryngeal squamous cell carcinoma and 10 cases of polyps of vocal cord tissues. Results The positive rate of NF-κB and the counts of lymph ves-sels in laryngeal carcinoma[60. 0% ,( 13.3±3.4)/HP]were significantly higher ( P <0. 05 and P <0. 01respectively) than those in polyps of vocal cord tissues[10.0 % ,(6. 1±3. 8)/HP]. The positive rate of NF-κB and the counts of lymph vessels in well differentiated adenocarcinoma and cases without metastasis were significantly lower( P < 0. 05, P <0. 01 ), compared with poor-differentiated adenoearcinoma and ca-ses with metastasis. The counts of lymph vessels in the NF-κB positive cases were significantly higher than thoseinNF-κBnegativecases[(14.9±4.1)/HPvs (9.8±3.1)/ HP, P <0.01] . Conclusions The expression of NF-κB and the counts of lymph vessels might be important markers to be used to monitor the progression, biological behaviors, metastatic status and prognosis of laryngeal carcinoma. NF-κB might pro-mote lympoangiogenesis in laryngeal squnmous cell carcinoma tissues.
